Avoid installing an outlet that directly faces the wind and rain. The terminal will generate noise and pollution, and it must be installed in an eco-friendly space that preserves its surroundings. The air inflow terminal must be adequately positioned away from polluting sources. Combustion air streams must not contain halogens (chlorine, bromine, fluorine, etc.) Freon, chlorofluorocarbons (CFCs) or sea salt, to avoid damaging the operating health of the combustion appliance and/or permanently alter its service life.
